The above linked article talks about a developer who programmed his Roomba to swear when it bumps into things. If it’s going to “feel like a part of the family, he better learn to swear like the rest of us.”
I miss my Roomba. I used to talk to it. Encourage it. Apologize for being in its way. I think it ended up in storage when we moved. Maybe someday, I’ll have it to keep me company again.
